AUTOMATIC SELF-IGNITING GAS-BURNER.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed July 21, 1905. Serial No. 270,736.

To all whom it may concern:

Be it known that I, OTTO STRULLER, a citizen of the United States, residing in the borough of the Bronx, city of New York, county and State of New York, have invented certain new and useful Improvements in Automatic Self-Igniting Gas-Burners, of which the following is a specification.

This invention relates to an improvement in automatic self-igniting gas-burners, and

its principal object is to simplify the means for igniting the gas, particularly with a view to promptness of action.

Heretofore self-igniting gas-burners have been constructed with many complicated and intricate parts, which were not positive in action, and in many cases are impracticable; whereas in my invention, all these difliculties are overcome by the simplicity of construction and operation of the device One of the objects of this invention is therefore to provide means for releasing a gas-cock from its seat after a movement of the gas-cock in the first operation of supplying gas to the ignition cylinder.

Another object is to provide means controlled by a movement of the cock, for regulilting the supply of gas to the ignition cylinc er.

WVith these and other objects in view, the

invention consists in certain constructions and combinations as will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.

In the drawings forming part of this specification, Figure 1 is a sectional view showing the position of the channels when ,the cock is closed, also the position of the ignition pill in the ignition cylinder. Fig. 2 is a sectional view showing the position of the channels when the cock is turned onsufficient to allow gas to pass through the channels to the ignition cylinder. Fig. 3 is a sectional view showing the position of the chan nels when the cock is turned on full, and allowing the full pressure of the gas to pass through the channels to the gas-burner. Fig. 4 is a front elevation of the improved device. Fig. 5 is a side elevation of same. Fig. 6 is a section on line 6, 6, of Fig. 4.

In the several views like parts are identified by like signs.

Referring to the drawings, 1 indicates the body of the device, which may be greatly varied in construction. 2 indicates the externally threaded projection for fastening the tip 3 thereto, and 4 the burner secured to the other end of the tip 3 by the ordinary means. An internally threaded socket 5, on one side of the body 1, is adapted to be sesured to the supply pipe 6. The channel 7, leading from the socket 5, is adapted to supply the gas through channels in a cock to be hereinafter described, and through the channel 8 to the gas-burner 4, and through the channel 9 to the channel 10; the said channel 10 being formed in the projection 11 on the side of'the body 1.

A tube 12 secured in the channel 10, supports an ignition cylinder 13, close to one side of the gas-burner 4. The upper end of the ignition cylinder 13 is situated a proper distance below the gas-burner 4 to allow the escaping gas from'the burner 4 to be ignited by the preliminary flame from the igniting cylinder 13. An ignition pill 14, is secured in the ignition cylinder 13, close to the orifice in the tube 12, so that the gas cannot escape through the tube 12 into the ignition cylinder 13, without coming in contact with the ignition pill 14. The gas when passing through the tube 12 into the ignition cylinder 13, comes in contact with the ignition pill 14, and causes the platinum wires 15 to become incandescent, thereby igniting the gas and a flame is carried up through the ignition cylinder 13, to the burner 4. Air holes 16, in the ignition cylinder 13, facilitate the igniting of the gas in passing through the ignition cylinder 13. The adjusting screw 17 screwed in the channel lO, on the under side of the projection 11, is adapted to regulate the flow of gas through the channel 10 to the tube 12.

A cook 18 of the ordinary kind is seated in the body 1, and is held in operative contact with the seat 19 by means of the threaded screw 20 and spring 21; the said spring being seated in the recess 22. A projection 23 fixed to the cook 18, is adapted to engage with the indicator stop 24 formed on the front of the body 1. The indicator stop 24, is so situated that, when the projection 23, of the cook 18., comes in contact with the indicator stop 24, there is a free passage of gas from the channel 7 of the body 1, through the channel 25, formed in the cook 18, to the tube 12 supporting and connected to the ignition cylinder 13. It is desirable that the cook 18 be operatively secured to the seat 19, and also to be released from the seat 19 during part of the operation of the cock, 18, without allow- 1 further operate the cock 18 beyond the indi- I cator stop 24, on the body 1, to allow the gas from the channel 9, thereby extinguishing the flame in the ignition cylinder 13.

Variations in construction, arrangement, and operation of parts may be resorted to within the scope of my invention, and portions of my improvements may be used without others.

Having thus described my invention, I claim 1. In a gas igniting device, the combinato flow through the channels into the burner tion of a burner, a pilot tube having a self- 4, it will be necessary to compress the spring 21. This compression is eifected by turning the cook over the indicator stop 24, thereby compress ing the spring 21 and releasing the cock 18 from the seat 19. When the projection 23 on the cock 18, has passed beyond the indicator stop 24, the spring 21 forces the cock 18 back to its seat.

The operation of the device is as follows: as shown in Fig. 1, the device is in'its normal condition, with the cook 18 turned off. In

' order to ignite the gas, the cock 18 is turned until the projection 23 011 the cock 18 comes in contact with the indicator stop 24 on the body 1, the channels are then in the position as shown in Fig. 2. The gas now escapes through the channel 7, and passes through the channels 25, 9 and 10, up through the tube 12, and comes in contact with the ignition pill 14, which becomes incandescent and ignites the gas passing through the ignition chamber 13. i

The principal object of the indicator stop 24, is to engage the projection 23, thereby preventing the movement of the cook 18 for a short period of time, in order to allow the gas in the i nition chamber 13 to ignite before the 000 i 18 is turned on full, to allow the gas to pass through the channel 8 leading to the burner 4. It is clearly seen in Fig. 2 that the gas also escapes through the small opening 28, formed in the end of the channel 25 leading to the channel 8. When the gas is ignited in the ignition cylinder 13, the gas escaping through the burner 4, is ignited by the flame from the ignition cylinder 13. The cock 18 is now turned on full as seen in Fig. 3, which permits the gas to escape through the channels 25 and 8, and cuts off the gas 18 until the projection 23 is forced igniting body adjacent to the burner, a cock having an angular passage for controlling the admission of the gas to both the burner and tube, a stop, a projection carried by the cock adapted to contact with said stop when the.

cock is revolved to bring the angular passage in communication with said tube, and means .providmg for a limited longitudinal movement of the cock whereby the projection may override the stop and bring the said angular passage into communication with the burner by j the further revolution of the cock.

2. In combination. with a gas burner, a self-igniting device therefor, a cock having a passage for controlling the admission of the gas to both the burner and ignition device, a

stop a projection carried by the cock adapted to contact with said stop when the passage is in communication with said device, and means providing for a limited longitudinal movement of the cock whereby the projection may override the stop and bring the said passage into communication with the burner.

3. In combination with a gas burner, a self-igniting device therefor, a cock having a passage for controlling the admission of the gas to both the burner and ignition device, means obstructing the further movement of the cock when the said passage is in communication with said device, and a spring normally forcing the cock to its seat and permitting of the same to be longitudinally moved against the tension thereof whereby the cock may be moved beyond said obstructing means and bring the said passage into com munication with the burner.
